Warning
If a coil containing device is connected, e.g. a relay / electromagnetic lock, it is necessary
to protect the intercom output against voltage peak while switching off the induction
load. For this way of protection, we recommend a 1 A / 1000 V diode (e.g., 1N4007,
1N5407, 1N5408) connected antiparallel to the device.
